What Causes Abnormal Noise When Starting the Engine?

When starting the vehicle, the reasons for abnormal engine noise include: 1. Premature connection of the electromagnetic switch main contacts: The starter makes abnormal noise when the starter drive gear has not yet engaged with the flywheel ring gear. 2. Poor contact of the electromagnetic switch: The rotor collides with the magnetic pole, the brushes are excessively worn, or the electromagnetic switch has poor contact. 3. Drive gear failure to disengage: The drive gear fails to disengage and continues to operate. Even after turning off the ignition switch and cutting off the power, the starter still runs, and a screeching sound occurs immediately after the engine starts. The starter is dragged at high speed and cannot stop or takes a long time to stop, causing the starter to sweep and burn out.
